NE 431: Radiation Protection
Course Outline:
-
Review of Nuclear, Atomic Physics
-
Bohr’s atom, excitation, ionization, basics of wave mechanics, the Nucleus,
binding energies, alpha, beta decay, gamma emission
-
Radioactive Decay
-
Review of basic concepts (half-life, decay constant, description of radioactive
decay), series decay, statistics of decay
-
Interaction of Heavy Charged Particles with Matter
-
Energy-Loss mechanisms, Bethe’s formula, scaling of stopping powers, range,
slowing-down time
-
Interactions of Electrons with Matter
-
Energy-Loss mechanisms, collisional and radiative stopping power, radiation
yield, range (straggling)
-
Interactions of Photons with Matter
-
Interaction mechanisms, photoelectric effect, Compton effect, pair production,
cross sections, attenuation, energy transfer and absorption coefficients
-
Neutrons
-
Classification of neutrons, neutron sources, interactions with matter (elastic,
inelastic scattering), slowing down, fission ( induced, spontaneous), nuclear
reactions.
-
Radiation Detection
-
Ionization in gases, semiconductors, scintillators ( organic, inorganic),
detector types, detection of neutrons, statistics for radiation detection
-
Radiation Dosimetry
-
Review of quantities and units, exposure and dose measurements, alpha,
